SPECIFICATION forming part of Letters Patent No. 526,838, dated October 2, 1894. Application filed July 14, 1894'. serial No. 517,586. (remodel.)

.To all whom it may concern.-

Beit known that I, zen of the United States, residing at Boise City, 1n the county of Ada and State of Idaho,

have invented certain new and useful-Imel provements in Oil-Oups for SteamEngines; and I do declare the following to bel'a full, clear, and exact description of the invention, such as will enable others skilled in 'the art to whlch it appertains to make and use the same.

This' invention has -relation`to improvements 1n devices for holding oil, grease, land other lubricants, 'and feeding the same under parts\ of machinery, and ls'more particularly adapted to be ap.

pressureto the moving plied to the crank 'pin steam engine. l Y

The many objects and advantages will lappear from the following description and claims and cross head Aof a when taken in connection with the annexed` drawings, -in which- Figure l, is a perspective view of the improved device'illu'strating the parts in the assume when all orfaA part of the lubricant has been eX#y position which they pelled from the cup. Fig. 2, is a vertical, central, sectional View of the same.y Fig. 3, is a vertical, sectional view taken in the plane indicated by the dotted line m,'onFig. 2,with a part of the cup broken away. Fig. 4t, is a perspective view of the stirrup for receiving the screw valve, and Fig. 5, is a perspective view of the lever for sustaining the stirrup and operating the bell hammer.

Referring by letter to said drawings: A, indicates the cupvforh'olding the oil, grease, or other lubricant. This cup may be ofv any suitable capacity and composed of any suit.

able material, having a cylindrical bodyl a, which is externally screw threaded at oppo-v tical slot. is a notch or offset recess g. Y

Within the cupis a snugly fitting piston O,

JOHN P. HUNTER, a citi-` which has secured to it a vertically-disposed hollow stem D, which may be connected by a screw joint, or otherwise. out through I the aperture d, in the screw cap of the cup and is curved laterally as shown at h, to pass through the vertical slot of the upright e, and thence curves downwardly as shown'at t', to receive on its free end, a gong or bell E.' Said stem is open at the upper end of its vertical branch to provide a filling aperture and said aperture is normally closed by a stopper as shown.

Interposed between the upper side of the piston C, within the cup, and the under side of the screw cap, is a spring F, which is here shown as of a conical form so that it may nest when fully contracted, although itisobvious that other forms of springs might be used.

The bottom of the cup is covered by a disk or plate G, which is also screw threaded to receive the screw thread c, of the cup, and this plate is provided with a central, vertical aperture 7c, and'surround'ing the aperture on the under side -is an externally threaded boss Z, and-depending centrally from this boss is a tube m; the'aperture extending through the bossand tube, as shown. Theaperture lo', through the bottom of the cup is countersunk or provided with a concavity fn., at its upper end," so as to receive the conical head 19,' of the screw valve H, arranged. therein. This valve may comprise an ordinary screw hav- This stem passes Y ing a'kerf q,'to receive a screwdriver or other l imple'mentrfvor adjusting the discharge of the feed.

I, indicates anozzle or base section. This nozzle is screw 'tapped at its upper end as shown ata, and is designed to be -screwed on to the threaded boss Z, of the plate G, and is it so las to regulate 'provided at its-lower-end with a discharge nipple 'K.4 Thechamber L, of the nozzle, extends for a sufficient distance and is'then providedwith avconical base s, from the center of which the discharge passage or aperture t, extendsout through the' discharge nipple, and the nipple is externally Yscrew threaded asfshown at u, so that it may be screwed on tojthe crank pin or cross head of an engine' or other suitable part of -machinery to be lubricated. The nozzle is provided at IOO 2 seasss one side with a lateral bracket M, which may be formed integral therewith and above this bracket arm is a lateral slot N.

P, indicates a lever. This lever is of a peculiar construction having a ring o, at its inner end which is designed to surround the tube m, and it is provided at its outer end with a Hat head w, for a purpose which will presently appear. The lever is pivoted at a suitable point in its length in the lateral aperture N, as shown, and the ring is provided at diametrically opposite points with notches or seats Q, R, has its two branches S, provided at their free ends with lateral lugs t, to bear in the notches Q, of the ring of the lever I), and said yoke is provided in its vertical center with a screw tapped aperture T, which is designed to receive the screw threads of the valve I-I, It will thus be seen that the valve can be adjusted in the outlet aperture of the cup.

U, indicates a spring which may surround the tube fm, and bears at opposite ends against the boss and the upper side of the inner end of the lever I), so that it will tend to depress said lever at theinner end and consequently the stirrup carried thereby which supports the valve.

Extending horizontally from the bracket arm M, is a branch V, which is screw tapped to receive the threaded stem of a set screw W, and this branch and set screw assume a position below the fiattened head of the lever l?.

Y, indicates a bell hammer. This hammer is provided at its upper end with a suitable head, and its lower end is pivotally connected with the bracket arm M, preferably by means of a curved `arm O, and the lower end of said hammer is designed to come into contact and rest upon the outer end of the lever I), and said hammer is arranged just below the bell or gong E.

In operation, it will be seen that by taking hold of the stem of the plunger, and drawing it up in the slot f, of the upright until it reaches the outset g, the spring F, within the oil cup will be contracted, and the plunger can then be removed by simply screwing oft' the cap B. IVhen the cap has been removed, should it be desirable to adj ust the valve H, so as to change the discharge of the lubricant, this can be done very quickly by the manipulation plement placed in the kert of said valve. The grease or oil should then be placed in the cup and the screw cap replaced, and the stem of the plunger taken out of the odset in the upright when the spring F, will be allowed to act and will force the grease or oil down around the valve and out through the discharge until all of the contents have been expelled. At this point or just before all of the lubricant has been discharged, the bell Vor gong descending, will come in contact with the hammer, and as the motion of the engine will keep the hammer vibrating, an alarm to receive the stirrup R. This yoke of a screw driver or other in` will be given to the attendant, and the bell or gong will continue to ring until the piston has been raised in the cup. By reason of the set screw W, the hammer can be raised or lowered with respect to the bell or gong so as to adjust the same for action, and by reason of the spring U, the lever although seated upon the set screw at its outer end, and the hammer bearing thereon, it will effectively cause a vibration ot' said lever during the movements of the engine, and will consequently impart such vibratory motion tothe hammer.

While I have given a very full and detailed description of the various parts, and the exact manner in which they are combined and connected, yet I do not wish t'o be understood as con ining myselt1 to the exact construction and combinations shown and set forth, as I am aware that many of them might be modified without departing from the spirit of my invention.

Having described my invention, claim is 1. In a forced feed lubricator, the combination with a cup, having a suitable discharge; of a piston movable in said cup, and having a stem, a gong carried by said stem and a hammer in the path of movement of said gong, the hammer and gong being designed to contact as the lubricant has been discharged from the cup, substantially as specified.
